[PATCH v2 2/2] bsp/raspberrypi: Mini UART driver

This patch adds driver for Mini UART present in Raspberry Pi 3 and above, this UART is currently used as the primary UART in these models. The Mini UART is similar to ns16550, this driver is built upon libchip/ns16550. --- bsps/arm/raspberrypi/console/console-config.c | 117 -- bsp

[PATCH v2 1/2] libchip/ns16550: Allow user calculate baud divisor

This patch will allow the user to pass a function to calculate the baud divisor. This will allow for more flexibility, since for some BSPs like raspberrypi, the calculation of baud divisor is different from what is in the current driver. --- bsps/include/libchip/ns16550.h | 9 +++--

Re: [PATCH v3] doc/raspberrypi: Added instructions for raspberrypi

Hello Niteesh, you had two different "v3" patches. Therefore I missed this one. I thought there was still a review comment from Gedare pending (which he added at the v2 patch but after the first v3 has been sent). On 12/01/2020 19:47, G S Niteesh wrote: > Added instructions to run examples on ras

I can try QEMU. Is there a quick pointer to the QEMU parameters needed to run a Pi2 image? Alan On Tue, Jan 21, 2020 at 3:22 PM Christian Mauderer wrote: > > Does the same error occur on the Pi2 Qemu? In that case you could use it > for proper debugging. > > On 21/01/2020 03:35, Alan Cudmore wrot

Re: [PATCH v2] Raspberrypi: updated the console interface.

Hello Niteesh, yes, sorry. At work I only put a limited time to the mailing list as long as the patches are not work related and privately I'm currently quite busy with another project (will be better after 01.02.). Therefore I didn't have a look yet. I'll take a look at the patches. I think there

Re: Raspberry Pi test report

Does the same error occur on the Pi2 Qemu? In that case you could use it for proper debugging. On 21/01/2020 03:35, Alan Cudmore wrote: > I don't really have a debug setup.. I'm just using printk for now. But > I have a pretty efficient setup where I can add a few printk > statements, rebuild and
